Custom Shopify apps for the workflow your store actually runs.
When an off-the-shelf app is close but not right, or your store needs to talk to an ERP, CRM, warehouse, or internal tool, I build custom Shopify apps around the exact requirement.
The approach
Technology in service of a clearer business outcome.
A good Shopify app respects the platform's realities: API rate limits, webhooks that can arrive twice or late, and extension points that change between versions. I design for those so the app keeps working as order volume grows.
You work directly with me from requirements through launch. That keeps product context close to technical decisions and avoids the gaps that appear when strategy, interface, backend, and deployment are treated as separate problems.
What I can build
Focused capabilities for a complete result.
The scope is shaped around your users, operating reality, and the smallest responsible path to value.

Common questions
Shopify App Development FAQs
What is the difference between a custom app and a public app?+
A custom app is built for one store or organization and installed directly. A public app is listed on the Shopify App Store for many merchants and goes through Shopify's review. I can build either.
Can a custom app connect Shopify to our ERP or warehouse?+
Yes. Orders, inventory, products, and customers can sync through the Admin API and webhooks, with retries and logging so failures are visible.
